= Using CAN bus =

The IGEP0022 expansion board provides a CAN interface using MCP2515.

Several tools are provided by socketCAN to use this controller:

*candump: dump traffic on a CAN network.

*cansend: simple command line tool to send CAN-frames via CAN_RAW sockets.

*cangen: CAN frames generator for testing purpose.

*canplayer: send CAN frames from a file to a CAN interface.

In order to test the CAN interface you can connect IGEP0022 to a CAN device or network or to another IGEP0022 board.

In the last case, you have to connect the two boards like this:

pin number) (pin number

4) O----------------O (4

Now you can set up the interface (on all boards when using multiple IGEP0022 connected to a CAN network simultaneously):

/sbin/ip link set can0 up type can bitrate 125000

can0 1F334455 [0] remote request

Switch roles and do try it again
